Scattering Properties of a Suspension Containing Plate-Like Particles and their Aggregates

The results of the scattering matrix measurements at a wavelength of 0.63 μm are presented for an aqueous suspension of lead oxide containing plate-like particles and their aggregates with monomers dimensions of ~ 5 nm. The results of the measurements are compared with the matrix calculations for ax...
